A novel multi-functional tool with circumferential notches shape probe was proposed for friction stir lap welded dissimilar materials. The novel probe produced larger turbulent flow region (strain rate ≥10 s−1) by 185% and converged the plasticized materials below the probe top. The general hook and cold lap defects were eliminated, and the large metallurgical bonding area was acquired. The tensil...... hiện toàn bộ
